avoid grade F x402 endpoint found on CDP Bazaar delisted confidence 0.20
https://k2so.wrong.systems/api/services/casper-agent-payment-settlement-verification-pro

As of 2026-08-15, k2so.wrong.systems/api/services/casper-agent-payment-settlement-verification-pro was unreachable or returned errors on every one of its 2 reliability checks since first seen 2026-08-13 (2 days). Its x402-trust grade is F (score 22.2 from limited data so far, tracked for 2 days), so it is best avoided for now. It is no longer listed in the x402 directory.

Advertised descriptionPay 0.002 USDC on Base for a machine-readable procedure that verifies whether an agent payment on the Casper rail actually settled. Triggered by CSPR Foundation momentum: csprUSD rebuilt for agent payments, Casper listed on Kraken, and a seat at the x402 Foundation. Covers the csprUSD and native CSPR paths separately, the settlement-address stability check across two probes, deployment finality semantics on Casper (era-based finality, not instant), the explorer and RPC endpoints to sample(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)

Cached snapshot, computed 32 hours ago. This is the full-density trust score computed from every probe, same as the paid API... but it may be up to 24 hours old. For a guaranteed-current answer it re-probes the endpoint live at the moment you ask, adds a confidence band, the full component breakdown, structured risk flags and on-chain settlement proof:
Browser wallet payment, no code required. Agents use POST /v1/x402-trust or the x402_trust_score MCP tool.

Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint; a geographically distant endpoint reads slower even when its server is fast, so it is only lightly weighted in the score.

This is the free cached snapshot. Here's what the paid API adds.
  • ✓
    Live probe at decision time:
    We re-check the endpoint the moment you ask (timestamped) and compute the score from all scores up until this moment, instead of this cached snapshot that may be up to 24h old.
  • ✓
    Confidence band, full component breakdown & structured risk flags:
    Exactly why the score is what it is, machine-readable.
  • ✓
    On-chain settlement proof:
    Real USDC volume & distinct-payer count for the payTo wallet: is anyone actually paying it?
  • ✓
    90-day raw history:
    Every listing/price/payTo change and probe result (via POST /v1/x402-history), up to 90 days back.
  • ✓
    The ranked better-scored alternatives:
    The resource URLs, scores & prices we don't reveal above (via POST /v1/similar), if there are better alternatives available.
  • ✓
    Change & liveness alerts:
    Get notified on payTo/price changes, spec regressions or downtime (via POST /v1/watch-endpoint-30d). Connect up to 10 Discord / Slack webhooks or poll regularly with bearer auth. Increases probe-density to every 5 minutes instead of the usual 30 for the watched endpoint.

... Simply give your agents the tools to do all of that for you, with a simple command
$npx -y x402-trust-mcp

Prefer HTTP? Call POST /v1/x402-trust directly (pay-per-call over x402, from $0.005).
